Answer:
Two possible equations:

The system has 0 solution as parallel lines never cross each other.
Step-by-step explanation:
Considering the two lines are parallel, they both have the same slope.
let m be the slope of the two lines:

are the value on y axis where the two lines cross the axis.
Because the lines are parallel, there exists no point that lies on both lines, therefore the system has 0 solution.
138 Degrees because it’s supplementary so 180 - 42 = 138
